It's unlikely to be just one thing. The price is reasonable for what you paid and what the buyer gets, but it's more money than what many people are willing to pay at this point. Second, the shipping cost is very high. Three, whether it's fair or not, AV123 has been getting a lot of negative press recently, including in the area of QC, so that may turn people off. Four, the LS6's are large speakers w/ relatively low WAF. Five, not everyone here is looking for the type of big, dynamic sound the LS's provide. This is a very varied forum w/ a lot of different tastes. Just look at all of the circles and that becomes abundantly clear very quickly. And finally, the LS's are just not the right speaker for a lot of rooms. From the pics I've seen on the TCA forum, many people have the LS's close to the walls. And even with room treatments, that's not an ideal position for them, and it's very difficult to get the best possible sound from them.
So, a bunch of different things.
